The short version

  • Only BigQuery ML has a free tier, so it costs nothing to try first.
  • Each has a real cost: BigQuery ML not available in BigQuery's Standard edition, so the cheapest tier cannot use it; Copy.ai chat plan (lowest tier) available monthly, but Growth/Expansion/Scale plans require annual billing with no monthly option
  • They diverge on capability: BigQuery ML covers SQL-based ML, Copy.ai covers AI copywriting.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

BigQuery ML

  • Not available in BigQuery's Standard edition, so the cheapest tier cannot use it
  • Billed through BigQuery compute and storage rather than as its own product, so training cost tracks data scanned
  • Remote models incur extra Agent Platform charges on top
  • Externally trained model types such as boosted trees and AutoML run through Agent Platform rather than inside BigQuery

Copy.ai

  • Chat plan (lowest tier) available monthly, but Growth/Expansion/Scale plans require annual billing with no monthly option
  • Workflow credits system complexity requires calculating credit consumption based on workflow complexity; rates not published
